Why won't turbotax complete form 843 for excess social security tax withheld?

[MindyB]

Form 843 can be completed on paper and filed if needed.  Most taxpayers can claim the excess amount on Schedule 3 Line 11, but if your situation requires the form (usually a single employer that over-withheld), you can find it here: IRS Form 843: Claim for Refund and Request for Abatement
